Exploratory well soil sampler

Abstract

The invention relates to a soil sampler for an exploratory well and belongs to the technical field of soil sampling equipment. The soil sampler comprises a soil containing cavity, wherein the soil accommodating cavity is in a hollow cylinder shape, a soil sampler cutter is fixedly mounted at a bottom end of the soil accommodating cavity, a soil sampler connector is fixedly mounted at a top end ofthe soil accommodating cavity, the soil sampler connector comprises a circular ring, a plurality of middle rods and connecting rods, the middle rods are fixedly installed on the circular ring and arranged in the radial direction of the circular ring, the multiple middle rods are gathered at the circle center of the circular ring and fixedly provided with the connecting rods, the connecting rods are arranged in the direction deviating from the soil sampler cutter in the axial direction of the circular ring, and a top end of the circular ring of the soil sampler connector is further provided with a gravity hammer arranged on the connecting rods of the soil sampler connector in a sleeving mode. The sampler has the effects of simple structure, convenience in carrying, high sampling efficiency,few requirements on operators and simple production process.

Description

technical field [0001] The invention relates to a well soil sampler, which belongs to the technical field of soil sampling equipment. Background technique [0002] After the exploratory well is excavated and formed, soil samples need to be taken for geotechnical test analysis. At present, the method of manual excavation of the exploratory well and manual sampling of the exploratory well is basically adopted. Exploration wells are excavated at different depths, ranging from less than 1 meter to several meters. During the sampling process of the exploration well, if the exploration well collapses, it is easy to cause casualties, and the roads in the general excavation area are not smooth, making rescue extremely difficult. [0003] Chinese patent discloses a soil sampler (CN210051575U), a deep groove slurry sampler (CN201510528504), an undisturbed soil sampler (CN209495872U) and a loess undisturbed soil sampler (CN209372461U). Considering different sampling depths, portabilit...

Exploration wells are excavated at different depths, ranging from less than 1 meter to several meters. During the sampling process of the exploration well, if the exploration well collapses, it is easy to cause casualties, and the roads in the general excavation area are not smooth, making it extremely difficult to rescue

[0003] Chinese patent discloses a soil sampler (CN210051575U), a deep groove slurry sampler (CN201510528504), an undisturbed soil sampler (CN209495872U) and a loess undisturbed soil sampler (CN209372461U). Different sampling depths, portability, sampling success rate, etc. can be considered comprehensively. In order to meet the above requirements at the same time, there is room for improvement in the current scheme of soil sampler for exploratory wells.
